I got married 8 months ago. I knew that wife has a block in her heart and her surgery happened 4 years ago in 2011. She takes tablets for blood pressure. By knowing this should we take the chance for pregnancy? We consulted to doctor too who did the heart surgery but he said that it's risky and 50-50 chance is there. Doctor also said that he will not take the responsibility if anything happened during pregnancy . Please give us advice. help appreciated. thanks
